About KYN28A-12

KYN28A-12 is a relatively common high-voltage switchgear at present, rated voltage is 3.6kV~12kV. The equipped vacuum circuit breaker is in the middle of the switch cabinet, that is, the circuit breaker is located in the middle of the front cabinet of the switchgear, so the lower space can be saved for the expansion of other schemes or used as a cable room.

Application Channels:

Mainly used in power plants, substations, transformation and distribution centers of industrial and mining enterprises, and large-scale high-voltage motor starting equipment, etc., for receiving and distributing electric energy, and for controlling, protecting and monitoring circuits.

KYN28A-12 Parameters

Strict Quality Control

1. Equipped with a ±0.1mm high-precision industrial robot, it achieves millimeter-level control of switchgear bending and assembly, achieving a component standardization rate of ≥99% and a dimensional qualification rate exceeding 99.5%.

2. The cabinet body is constructed from 316L stainless steel with a nano-ceramic coating, processed and formed, and assembled using high-strength bolts, nuts, and rivets.

3. Compatible with various brands of circuit breakers, including components from brands such as ABB and Siemens, including the domestically produced ZN85-40.5 (3AV3) vacuum circuit breaker and Schneider's HVX series, to meet diverse user needs.

4. Each functional compartment in the switchgear is separated by metal partitions and equipped with independent pressure relief ducts.

5. Circuit breaker, earthing switch, and other operations can be performed with the high-voltage compartment door closed, allowing for closed-door operation.

6. Full-Scenario Verification and Intelligent Logistics System:

Cabinet Parallel Testing - Real-World Simulation

Full-Scenario Simulation Testing: Load Simulation, Emergency Operation Verification (Opening and Closing Response Time ≤ 20ms)
